The W-227 In-Ground Electronic Dog Fencing System is a no name brand, cheaply made fence and one I don’t recommend.

Before I go into the details of this dog fence and why it is not one I recommend, let me draw your attention to the in-ground fences that I rate very highly (click on any of them to read the full review):

The PetSafe PIG00-13661 In-Ground Fence is PetSafe’s updated entry-level containment system and it’s a solid reliable fence that comes at an affordable price.

For under $200 you get a transmitter that’s powerful enough to cover up to 10 acres, a receiver collar that’s known for its durability and system that’s safe and effective for any dog in the 8-125 lb weight range.

Since 1991 PetSafe has devoted their time and efforts to making the highest quality pet products on the market. Their commitment to superior pet containment systems is second to none and they’ve developed a line of electric dog fences that’s known for its safety and reliability.

The DOGTEK EF-4000 is currently unavailable. A comparable alternative I’d recommend is the PetSafe Basic In-Ground Fence, PIG00-14582. It’s a solid, dependable underground dog fence that can cover up to 5 acres and costs less than $150. Read the full review on this PetSafe in-ground fence here.

What sets the Innotek SD 2100 Rechargeable In-Ground Pet Fencing System apart is that it offers high end features at a very affordable price.

This system is the least expensive underground dog fence on the market that offers a rechargeable collar. Along with that you get a solid transmitter that’s powerful enough to cover up to 25 acres and comes with a built in battery backup.

With more of the essentials and a reasonable price point, the SD 2100 is definitely a step up from Innotek’s entry level containment system, the SD 2000.
